Question

试图从同一文件夹中的另一个文件导入i Dictionary。

这是“流体”模块：

fluiddensitydict = {
    "Acetone" : 791/1000,
    "Ammonia" :604/1000,
    "Benzene":879/1000,
    "Butane":556/1000,
    "CCL4":1584/1000,
    "CO2":680/1000,
    "Ethanol":783/1000,
    "Ethyl_Acetate":902/1000,
    "Gasoline":750/1000,
    "Glycerine":1260/1000,
    "Hexane":659/1000,
    "Honey":1417/1000,
    "Kerosene":815/1000,
    "Methanol":787/1000,
    "n_octane":692/1000,
    "Olive_Oil":910/1000,
    "Oil_engine":885/1000,
    "Oil_light":910/1000,
    "Pentane":626/1000,
    "Propane":510/1000,
    "R_twelve":1310/1000,
    "R_twentyTwo":1190/1000,
    "R_OneHundredThirtyFour_a":1206/1000,
    "Water":997/1000
}

这是“主”模块：

import Fluid

for element in Fluid.fluiddensitydict():
    print(element)

FluidAnswer = input("\nWhich of these fluids would you like: ")

density = Fluid.fluiddensitydict.get(str(FluidAnswer))

for element in Fluid.fluiddensitydict():
    if element == FluidAnswer:
        print("your chosen fluid is ",element, "and it has the density 
:",density)

当我运行文件时，我得到消息：我得到错误： for Fluid.fluiddensitydict（）中的元素：TypeError：'dict'对象不可调用

fluiddensitydict已被定义为字典，但是您正在作为函数进行调用。您可以遍历键和值，并打印与input()值具有相同键的字典值：

import Fluid
FluidAnswer = input("\nWhich of these fluids would you like: ")
for element, density in Fluid.fluiddensitydict.iteritems():
    if element == FluidAnswer:
        print("your chosen fluid is ",element, "and it has the density :",density)

从同一文件夹中的其他文件导入变量时遇到问题。
